Re: Changing font of GtkSourceView changes font of GtkSourceMap

[Reuben Rissler <silrep emypeople net>]

I am not sure if this helps any:


#!/usr/bin/env python

import gi
gi.require_version('GtkSource', '3.0')
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, GtkSource, GObject, Pango

class GUI:
    def __init__(self):

        GObject.type_register(GtkSource.View)
        window = Gtk.Window()
        window.connect('destroy', self.on_window_destroy)
        pane = Gtk.Paned(orientation = Gtk.Orientation.HORIZONTAL)
        window.add(pane)
        s_view = GtkSource.View()
        pane.pack1(s_view)
        s_map = GtkSource.Map()
        s_map.set_view(s_view)
        pane.pack2(s_map)
        s_map.set_property('font-desc', 
Pango.font_description_from_string("Sans 3"))
        window.show_all()

    def on_window_destroy(self, window):
        Gtk.main_quit()


if __name__ == "__main__":
    app = GUI()
    Gtk.main()
